PV combiner box is used to bring together the output DC current of the PV array. It will combine the same solar panels which in series to form a PV array, supporting the use of photovoltaic grid connected inverter, so as to constitute a complete photovoltaic system, with the city electric grid.
By using PV array combiner box, according to the input voltage of the inverter, Clients can connect a fixed number of similar PV modules to form a PV array. Then different strings of PV array can be converged into the PV array string box. After that, together with lightning arresters and circuit breakers, it is connecting to the inverter to reduce the system installation time and increase the system safety.
